Safety valve
5.4 Electrical connections
All adjusting devices, verification and safety mechanisms were
submitted to a rigorous test in factory and are ready to work.
▶ Connect the appliance via a socket with earth connection.
5.5 Start-up
▶ Verify that the appliance has been correctly installed and
assembled.
▶ Open the water inlet valves.
▶ Open all the hot water taps in order to ensure all the air is
out of the connections.
▶ Control the tightness of all the connections and ensure that
the appliance fills to its full capacity.
▶ Connect the appliance to the electric current.
▶ Inform the customer of any user information of the
appliance and handling.
In order to avoid problems caused by sudden
pressure changes, we recommend the
installation of a non return valve at the
appliance
DANGER:
▶ Install a safety valve at the water inlet of
the appliance ( Fig. 9 and 10).
NOTICE:
NEVER OBSTRUCT THE PURGE OUTLET OF
THE SAFETY VALVE.
Never install any accessory between the
safety valve and the cold-water inlet (right
hands side) of the appliance.
If the pressure at the cold water inlet is
superior to that of 80% of the maximum
pressure of the appliance at, ie: 6,4 bar:
▶ Install a reducing valve (Fig. 9).
The safety valve will trigger every time the
water pressure in the appliance exceeds 6,4
bar. A facility for draining the expelled water
must be provided.
DANGER:
By electrical discharge!
▶ Before working on the electrical
components, firstly cut the power,
(fuse, circuit breaker or other).
CAUTION:
Electrical protection!
▶ The appliance should dispose of an
independent connection to the DB
board (electric board), protected by a
30 mA differential circuit breaker and
earthing.
The electrical connection must be realized in
accordance with the current country laws
regarding electrical installations.
